McAfee has significant market share in enterprise, where they've built a product that isn't necessarily good but largely meets compliance and management requirements more easily and more inexpensively than the built-in Windows features. What I mean here are remote management and monitoring features, across AV, host firewall, host IDS, DLP, SIEM, etc. I don't mean to defend McAfee as their products are, across the board, pretty terrible. But I think most of their revenue comes from a market that Microsoft has, so far, largely chosen not to take on: enterprise security departments with significant remote management and compliance requirements. You can only approach what McAfee provides with Microsoft products, and you'd need AD, SCCM and the whole nine yards (probably Azure AD and InTune these days). McAfee's major competition in this area is Symantec with Symantec Endpoint Protection (SEP). There aren't a lot of other vendors with an all-in-one solution. Consider, for example, that McAfee holds the contract with the Department of Defense for HBSS which is McAfee's endpoint solution with custom tweaks for DoD requirements.
